Changing climate and reforestation
January 10, 2016 08:24 AM - Asociación RUVID via ScienceDaily
For the past six years, researchers at the Universitat Politènica de València (Polytechnic Univeristy of Valencia, UPV) have been studying the performance of twelve Aleppo pine varieties native to different regions of Spain in reforestation campaigns across three national forest areas. Different varieties or genotypes have different levels of resistance to cold and drought, which influence how well they perform in a given geographical region, and researchers wanted to find out which varieties worked best and where.
To do so, the different national varieties or genotypes were used to repopulate forest areas in La Hunde, Valencia (as the control region), in the drier Granja d'Escarp, Lleida, to the north and further inland in Tramacastiel, Teruel, where the climate is much cooler.
"The varieties from Inland Levante and La Mancha performed the best overall, while those from further south seem to be perfect for reforestation efforts in regions already affected by climate change," observes Antonio del Campo, researcher at the UPV's Institute of Water and Environmental Engineering (IIAMA).
As gas prices fall, consumers going back to less fuel efficient vehicles
January 9, 2016 08:04 AM - Scott Horsley, NPR
There were high-fives this week from Detroit to Washington, D.C., as carmakers celebrated record auto sales.
Americans bought 17.5 million cars and trucks in 2015. That's a huge turnaround from 2009, and the Obama administration cheered the rebound as vindication of the president's decision to rescue General Motors and Chrysler from bankruptcy.
"Because of the policy decisions that were made by this administration to place a bet on those workers, America has won, and our economy has been better for it," White House spokesman Josh Earnest told reporters Wednesday.
New Federal dietary guidelines recommend eating less meat
January 7, 2016 12:17 PM - NRDC
Many Americans, especially men and teenage boys, eat too much red meat, poultry and eggs, and should reduce their consumption, according to new federal dietary guidelines jointly released today by the U.S. Department of Agriculture and the Department of Health and Human Services. Reducing Americans’ meat consumption will not only help improve public health, but reduce climate and water pollution from the meat industry.
This is the first time federal dietary guidelines have included a recommendation to reduce meat consumption. The report advises that cutting back on meat can reduce the risk of cardiovascular disease, obesity, type 2 diabetes and some types of cancer.
The new dietary advice, however, did not include the recommendation from the agencies’ expert scientific advisors that the FDA explicitly link the science-based benefits of adopting diets lower in red meat, and higher in plant-based foods, to additional benefits to environment sustainability and to food security.
Lawrence Livermore Laboratory developing underground battery system to store energy and CO2
January 6, 2016 04:30 PM - Lawrence Liverpool Laboratory.
Meeting the Paris Climate Agreement goal of limiting the increase in the global average temperature to well below two degrees Celsius compared to pre-industrial levels will require increased use of renewable energy and reducing the CO2 intensity of fossil energy use.
The intermittency of when the wind blows and when the sun shines is one of the biggest challenges impeding the widespread integration of renewable energy into electric grids, while the cost of capturing CO2 and storing it permanently underground is a big challenge for decarbonizing fossil energy.
However, researchers from Lawrence Livermore National Laboratory, Ohio State University, University of Minnesota and TerraCOH, Inc. think they’ve found an answer to both of these problems with a large-scale system that incorporates CO2 sequestration and energy storage.
Volunteering is good for your health!
January 5, 2016 06:11 PM - Eric Kim, Harvard School of Public Health
Eric Kim, a research fellow in the Department of Social and Behavioral Sciences at Harvard T.H. Chan School of Public Health, recently led the first study to look at a possible link between volunteering and health care use in older adults.
Why did you decide to study volunteering from a public health perspective?
There is a growing body of research showing that volunteering is associated with better physical health and mental health outcomes, as well as better health behaviors.
Another important reason is that the number of older adults in the U.S., and other countries, is rapidly rising. Over the next 35 years, the number of 65-year-olds is going to double. As a result, the number of chronic illnesses will likely rise causing at least two outcomes: First, there will be a large increase in the number of people suffering. Second, the rising number of illnesses is going to put a huge burden on our health care system. If volunteering does affect health care use, these findings could be used to inform new strategies for increasing preventive health screenings, lowering emergency room use and health care costs, and also enhancing the health of older adults.
Will Styrofoam Get the Plastic Bag Treatment?
January 4, 2016 07:09 AM - Kevin Mathews, Care2
Say farewell to Styrofoam take-out containers in the nation’s capital. It’s been a few years in the making, but Washington, D.C. has finally enacted a firm ban on polystyrene food and beverage containers. Henceforth, all restaurants will have to provide biodegradable alternatives if they want to send their patrons home with leftovers.
Solar gaining on coal in India
January 4, 2016 06:15 AM - Chris Goodall, Ecologist
A KPMG study shows that the cost of solar power in India, revealed by public auctions, is barely half a cent above that of cheap local coal , writes Chris Goodall, with generators bids falling well below 5p (UK) / 7¢ (US) per kWh. The idea put about at COP21 that India and other poor but sunny countries need coal to develop their economies is fast running out of steam.
When the accountants have fully loaded the network and other costs PV ends up as very slightly cheaper than using lndian-mined coal. And, of course, this advantage will grow as solar gets cheaper.
Commentators eager to arrest the move towards renewable energy are facing increasing difficulties finding arguments for the continued use of fossil fuel.
Good news about restoring river ecosystems
January 1, 2016 10:17 AM - Lizabeth Paulat, Care2, Care2
t is a commonly held belief that most ecosystems take about a lifetime to recover after damage is introduced by humans. However, researchers at Ohio State University are finding that initial recovery can be dramatic if the right conditions are present. The discovery was made while monitoring how dam removal impacted local species.
The studies focus on the reintroduction of birds and salmon to the habitat. What they found was that if just birds were introduced, they tended to have low weight and poor numbers of offspring. However, when dams came down and salmon and fish were put together, both species flourished and impacted the surrounding ecosystem positively.
Los Angeles area natural gas leak continues
December 31, 2015 05:06 AM - Lowell Williams, Care2, Care2
Though it seems to be oddly absent from the mainstream media headlines, a massive methane gas leak in Southern California’s Aliso Canyon has prompted thousands of evacuations and, since Oct. 23, has pumped over 150 million pounds of the greenhouse gas into the atmosphere. Even though the owners of the methane well, Southern California Gas Co., say this week that they have finally discovered the pipe associated with the leak, it will likely be months before a seal is entirely in place.
To truly underscore the seriousness of the Porter Ranch gas leak, the Environmental Defense Fund released an infrared aerial video this week showing the tremendous, continuous release of methane:
Methane gas, in its natural state, is also odorless. However, for safety reasons, foul-smelling additives are artificially included with the gas. In Porter Ranch, a Los Angeles neighborhood and the site of the leak, the additive smell’s intensity has affected the heath of many of residents — nose bleeds, nausea, headaches and dizzy spells have been reported.
This year's El Niño not giving up
December 30, 2015 05:12 AM - JPL-NASA
The current strong El Niño brewing in the Pacific Ocean shows no signs of waning, as seen in the latest satellite image from the U.S./European Ocean Surface Topography Mission (OSTM)/Jason-2 mission.
El Niño 2015 has already created weather chaos around the world. Over the next few months, forecasters expect the United States to feel its impacts as well.
The latest Jason-2 image bears a striking resemblance to one from December 1997, by Jason-2's predecessor, the NASA/Centre National d'Etudes Spatiales (CNES) Topex/Poseidon mission, during the last large El Niño event. Both reflect the classic pattern of a fully developed El Niño.
